Re: [MW:21214] Selection of consumable for SA537 CL2 bullets

By Materials & Welding
Hi!
In such case where you want to get min 550Mpa It is better to use
EA3 + F8A4 Flux (You can try with Thysen make UTV420TTR)
E8018D3 ,ER80SD2 But use proper higher side preheating temp and Post heating at 300-350 for 2hrs As in your case the thk is less and No PWHT

Hi,

Concern is over the minimum tensile properties for the welding consumable, the minimum for the welding consumable is 480-490 Mpa, where as for base material it is 550 minimum,, the difference of 60-70 Mpa is noted between these two minimum specified tensile values, the vendor proposal is to test the consumable to meet the base metal property, whether it is acceptable.(E7018-1/ER70S2/EH12K)



Thanks'
With Regards'

Hi!Yes the
consumable you have selected will give you the required
results (Impact value will be as per code using low heat
input  and hardness value can be achieved with proper
preheating of weld joint say min 125

  Hi,

suggestion required for slection fo welding comsumables for
AS 537 CL 2 material.

Requirments:

Design ; ASME SEC VIII DIV 2

Material: SA 537 CL2

MDMT : -35 C

PWHT : NO

Thk Shell : 32 mm

Carbon equivalent Max : 0.43

Hardness ; Less Than 248 HV 10

Process / GTAW/SMAW/SAW/FCAW

Whether E7018-1/ER70S2/EH12K can be tested at required
condtions for base metal and can be used or not.

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
